  • Abstract
  • Look Inside

We evaluated the long-term course of intraocular pressure (IOP) following laser iridotomy in 56 eyes with chronic angle-closure glaucoma (CACG) and 14 fellow eyes of acute angle-closure glaucoma (AACG) Kaplan-Meier's life table was used in the analysis. The posttreatment course of IOP was compared with the preoperative factors using Cox's multiple regression model. The end point of life table analysis was defined either as aggravation of IOP control needing more intensive medication or glaucoma surgery. During the average of 5.4 years of follow up, none of the fellow eyes of AACG reached the end point. In eyes with CACG followed up for 5 years, no further intensive medication was needed in 60% and no surgical intereven-tion became necessary in 89%. The posttreatment course of IOP was positively correlated with the PAS index, visual field loss and mean IOP level before treatment (p<0.05).
